My (extremely short) puzzle demo, Feedback wanted Options

[rewells]

Hey y'all. I'm learning to design puzzles, possibly looking to design a whole game. I'd like a little feedback. I'm specifically looking for feedback on how I evented the puzzles. Are their easier ways to set the puzzles up? There is some inconsistency in this regard, as I learned more as I progressed. So far I only have 5 rooms. All of the puzzles are straight up lifted from Brainlord for SNES, a game I highly recommend for puzzle designers. Here is the link.
